What is fiber optic cable termination




The purpose of fiber termination is to provide easy ways for fiber cross connection and light wave signal distribution. There are two types of fiber terminations: connector and splicing.
Fiber optic cable termination types:
Connector
Over the last two decades fiber industry manufacturers have developed at least a dozen types of fiber optics connectors. The typical ones are FC, SC, ST, LC, MU, SMA and MTRJ


Splicing types introduction
Mechanical splicing
Mechanical splicing is an optical junction where two fibers are precisely aligned and held in place by a mechanical assembly. Mechanical splicing aligns two fiber ends to a common centerline so the light can pass from one fiber to another.
Mechanical splices are best suited for multimode fiber applications. Some mechanical splices have been introduced for single mode fibers, but they usually have a higher insertion loss (typically 0.1dB).


Fusion splicing
Fusion splicing is an optical junction of two optical fibers by permanently welding them together with heat generated by an electronic arc (called arc fusion).
The fusion splicing process begins by preparing each fiber end for fusion. Fusion splicing requires that all protective coatings be removed from the ends of each fiber. The fiber is then cleaved with high precision fiber cleavers. In fusion splicing, splice loss is a direct function of the angles and quality of the two fiber-end faces
